7F simple chemical reactions
In this unit you will do a lot of different experiments with chemicals. You will find out the difference between a physical and chemical change.

Here are the learning objectives for this topic

I can
  • Name examples of physical changes
  • Name examples of chemical reactions
  • Do the Hydrogen test
  • Do the Carbon dioxide test
  • Name some carbonates
  • Write some simple chemical equations

I understand
  • That physical changes are reversible
  • That chemical reactions produce new substances and are irreversible
  • How we test for Oxygen, Carbon dioxide and Hydrogen
  • That a reaction between a metal and an acid produces a salt and hydrogen
  • That a reaction of an acid and a carbonate produces carbon dioxide, a salt and water
  • That oxygen, fuel and heat are needed for burning
  • That the reaction of Magnesium and Oxygen produced Magnesium oxide
  • That when a hydrocarbon burns carbon dioxide and water are produced.
